Direct Detection of Dark Matter Debris Flows

  title={Direct Detection of Dark Matter Debris Flows},
  author={Michael Kuhlen and Mariangela Lisanti and David N. Spergel},
  journal={Physical Review D},
Tidal stripping of dark matter from subhalos falling into the Milky Way produces narrow, cold tidal streams as well as more spatially extended ``debris flows'' in the form of shells, sheets, and plumes. Here we focus on the debris flow in the Via Lactea II simulation, and show that this incompletely phase-mixed material exhibits distinctive high velocity behavior. Unlike tidal streams, which may not necessarily intersect the Earth's location, debris flow is spatially uniform at 8 kpc and thus… Expand

Dark Matter Direct Search Rates in Simulations of the Milky Way and Sagittarius Stream
We analyze self-consistent N-body simulations of the Milky Way disk and the ongoing disruption of the Sagittarius dwarf satellite to study the effect of Sagittarius tidal debris on dark matterExpand
Under the FIRElight: Stellar Tracers of the Local Dark Matter Velocity Distribution in the Milky Way
The Gaia era opens new possibilities for discovering the remnants of disrupted satellite galaxies in the Solar neighborhood. If the population of local accreted stars is correlated with the darkExpand
The highest-speed local dark matter particles come from the Large Magellanic Cloud
Using N-body simulations of the Large Magellanic Cloud (LMC's) passage through the Milky Way (MW), tailored to reproduce observed kinematic properties of both galaxies, we show that the high-speedExpand
Empirical Determination of Dark Matter Velocities Using Metal-Poor Stars.
It is demonstrated that metal-poor stars are indeed effective tracers for the local, virialized dark matter velocity distribution and suggests that the bounds on the spin-independent scattering cross section may be weakened for dark matter masses below ∼10  GeV. Expand
Velocity substructure from Gaia and direct searches for dark matter
Data from the Gaia satellite show that the solar neighbourhood of the Milky Way's stellar halo is imprinted with substructure from several accretion events. Evidence of these events is found in "theExpand
Inferred Evidence for Dark Matter Kinematic Substructure with SDSS–Gaia
We use the distribution of accreted stars in SDSS-Gaia DR2 to demonstrate that a non-trivial fraction of the dark matter halo within Galactocentric radii of 7.5-10 kpc and $|z| > 2.5$ kpc is inExpand
Assessing Astrophysical Uncertainties in Direct Detection with Galaxy Simulations
We study the local dark matter velocity distribution in simulated Milky Way-mass galaxies, generated at high resolution with both dark matter and baryons. We find that the dark matter in the SolarExpand

Clumps and streams in the local dark matter distribution
A simulation that resolves dark matter substructure even in the very inner regions of the Galactic halo is reported, finding hundreds of very concentrated dark matter clumps surviving near the solar circle, as well as numerous cold streams. Expand
Detectability of weakly interacting massive particles in the Sagittarius dwarf tidal stream
Tidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing {approx}(0.3-23)% of the local density of our galactic halo. If theExpand
Dark matter direct detection with non-Maxwellian velocity structure

Exploring Dark Matter with Milky Way Substructure
Simulations reveal that dark matter in the authors' galaxy could be detected by the Fermi space telescope, and it is found that the annihilation luminosity from kinematically cold substructure could be enhanced by orders of magnitude relative to previous calculations, leading to the prediction of gamma-ray fluxes from as many as several hundred dark clumps that should be detectable by theFermi satellite.
